The Battle of Lepanto
"On October 7, 1571, a patchwork fleet of Catholic ships primarily from Spain, Venice and Genoa, under the command of Don Juan of Austria, was at a distinct disadvantage. The much larger fleet of the Ottoman Empire—a force with 12,000 to 15,000 Christian slaves as rowers—was extending toward Europe."
"However, St. Pope Pius V, realizing that the Muslim Turks had a decided material advantage, called upon all of Europe to pray the Rosary for victory. Christians gathered in villages and towns to pray as the sea battle raged; and at the hour of victory the pope—who was hundreds of miles away at the Vatican—is said to have gotten up from a meeting, walked over to an open window exclaiming “The Christian fleet is victorious!” and shed tears of joy and thanksgiving to God."
I am Baptist. That said, I am convinced that Lepanto was won due to those praying on the ships facing the Moslem Turks. And God honored those prayers.
